Background: The adverse reactions (ADRs) of targeted therapy were closely associated with treatment response, clinical outcome, quality of life (QoL) of patients with cancer. However, few studies presented the correlation between ADRs of targeted therapy and treatment effects among cancer patients. This study was to explore the characteristics of ADRs with targeted therapy and the prognosis of cancer patients based on the clinical data. Methods: A retrospective secondary data analysis was conducted within an ADR data set including 2703 patients with targeted therapy from three Henan medical centers of China between January 2018 and December 2019. The significance was evaluated with chi-square test between groups with or without ADRs. Univariate and multivariate logistic regression with backward stepwise method were applied to assess the difference of pathological characteristics in patients with cancer. Using the univariate Cox regression method, the actuarial probability of overall survival was performed to compare the clinical outcomes between these two groups...................
Background: With increasing cancer incidence and decreasing cancer mortality, there is a growing need for a valid and culturally adapted tool to measure health-related quality of life in children with cancer. This study validated the DISABKIDS Chronic Generic Module (DCGM-37) in Chinese children and adolescents with cancer. Methods: The DCGM-37 was translated and adapted for use in China following the guidelines from its copyright holders. In total, 140 children and adolescents with cancer and their guardians were included in this cross-sectional study. Internal consistency and test-retest reliability were evaluated. Convergent validity was examined using Pearson correlation between the DCGM-37 and the PedsQL 4.0 Generic Core Scale. Dimensionality was clarified using exploratory factor analysis. Discriminant validity was evaluated by comparing DCGM-37 scores by sex, age, family income, and clinical characteristics.......................
Background: Colorectal cancer (CRC) is one of the most common cancers worldwide; it is the fourth leading cause of death in the world and the third in Brazil. Mutations in the APC, DCC, KRAS and TP53 genes have been associated with the progression of sporadic CRC, occurring at defined pathological stages of the tumor progression and consequently modulating several genes in the corresponding signaling pathways. Therefore, the identification of gene signatures that occur at each stage during the CRC progression is critical and can present an impact on the diagnosis and prognosis of the patient. In this study, our main goal was to determine these signatures, by evaluating the gene expression of paired colorectal adenoma and adenocarcinoma samples to identify novel genetic markers in association to the adenoma-adenocarcinoma stage transition. Methods: Ten paired adenoma and adenocarcinoma colorectal samples were subjected to microarray gene expression analysis. In addition, mutations in APC, KRAS and TP53 genes were investigated by DNA sequencing in paired samples of adenoma, adenocarcinoma, normal tissue, and peripheral blood from ten patients. Results: Gene expression analysis revealed a signature of 689 differentially expressed genes (DEG) (fold-change> 2, p< 0.05), between the adenoma and adenocarcinoma paired samples analyzed. Gene pathway analysis using the 689 DEG identified important cancer pathways such as remodeling of the extracellular matrix and epithelialmesenchymal transition. Among these DEG, the ETV4 stood out as one....................
Aim: Fundamentally, aggressive care is considered to be avoided for the patients at the end of life. However, this is not always adhered in real-world practice. We attempted to determine whether, and if so how, the aggressive care is made for patients with ovarian cancer during the last month prior death. Methods : Enrolled were a total of 104 patients with ovarian cancer (including fallopian tube or primary peritoneal cancer), who were treated in Kuopio University Hospital in Finland during 2009-2014. The aggressive care was defined according to the standards outlined by the National Quality Forum; shortly, chemotherapy, emergency-room/intensive-care visit/admission, hospital admission, and death in hospital. Results : Two thirds of patients (67%) had received at least one form of aggressive care during the last month of their lives. Especially, admission in hospital in the last 30 days of life was the most common form of aggressive cancer care..................
As a kind of important innate lymphocytes in vivo, Natural killer (NK) cells have a rapid and efficient capacity to recognize and destroy tumor cells, senescent cells and virus-infected cells. In the past decades, NK cells have been widely applied in the treatment of hematological malignancies in clinic, even solid tumors. Successful results have been made against hematological malignancies (NCT00697671, NCT00990717, NCT00145626), but also a number of considerable challenges have been encountered during this period, such as poor outcomes in the treatment of solid tumors, difficult to migrate to and infiltrate into tumor sites, little functioning NK cell was seen in tumor stroma. Now we know tumor microenvironment has great influence on NK cell function, phenotype and activation, and it can finally give rise to NK cell dysfunction or/and exhaustion. Many strategies have been made to try to overcome those drawbacks. In this review, we discuss the current strategies to increase the NK cell-mediated tumor cell killing capacity and homing to the solid tumor site with the aim of heightening the clinical outcome in NK cell-based immunotherapy against solid cancer....
